We offer various adapters on which to mount Optical Tooling instruments and other alignment products. The 235-3 fits the intermediate tube on all of our heavy duty stands. The EasyConnect is a quick-release mechanism fitting 3 1/2″-8 threaded instruments. We have adapters designed for use with customer-supplied surfaces, some of which may be used with theodolites or total stations having a 5/8″-11 thread. Our various dovetail adapters are used in conjunction with our precision lateral cross slides and precision lifts.
